我在抓this页面。我正在访问以下HTML以获取部分详细信息:

<h2>
    <span class="mw-headline" id="Volume_one:_Quicksilver_.282003.29">Volume one:
        <i>
            <a href="https://en.wikipedia.org/wiki/Quicksilver_(novel)"
                class="extiw"
                title="w:Quicksilver (novel)">Quicksilver</a>
        </i> (2003)
    </span>
    <span class="mw-editsection">
        <span class="mw-editsection-bracket">[</span>
        <a href="/w/index.php?title=The_Baroque_Cycle&amp;action=edit&amp;section=1"
            title="Edit section: Volume one: Quicksilver (2003)">edit</a>
        <span class="mw-editsection-bracket">]</span>
    </span>
</h2>

我想抓住id Volume_one: Quicksilver .282003.29 。为此,我写了以下代码:

$sectionid = '#Volume_one:_Quicksilver_.282003.29';
print($crawler->filter( $sectionid ));

但它并没有返回细节,尽管它在那里。我哪里做错了?它确实很好地获取了#Epilogs部分。

请帮忙。

答案 0 :(得分:0)

你试过了吗?

print( $crawler->filterXPath('//*[@id='Volume_one:_Quicksilver_.282003.29']') );

我在FirFox浏览器中使用了“Inspect in FirePath”(安装了FireBug)来从该页面获取xpath。
